Diagnostic Procedure

Step

Inspection

Results

Action

1

PERFORM ACCELERATION SENSOR INITIAL POSITION LEARNING

•  Perform the headlight auto leveling system initial setting.
(See HEADLIGHT AUTO LEVELING SYSTEM INITIALIZATION.)

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Perform the DTC inspection for the auto leveling control module.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Perform the headlight auto leveling system initial setting again and perform the repair completion verification.

(See HEADLIGHT AUTO LEVELING SYSTEM INITIALIZATION.)

No

Go to repair completion verification 2.

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Perform the DTC inspection for the auto leveling control module.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [L.H.D. (E)].)

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the auto leveling control module, then go to the next step.
(See AUTO LEVELING CONTROL MODULE REMOVAL/INSTALLATION [(E)].)

No

Go to the next step.

VERIFY IF OTHER DTC IS DISPLAYED

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
